To all whom t may concern.'

Be it known that I, EBENEZER REGINaLn MORRIS, a subject of the King ofGreat Britain, residing at Sydney, in the State of New South Vales,Commonwealth of Australia, have invented certain new and useful Improvements in Riiie-Periscopes, of which the following is aspecication.

This invention relates to an improved rifle periscope, its object beingto enable a soldier or other person to aline the sights along the barrelof his rifle from one side thereof by reflection at right angles, whilehe is protected by earthworks, sandbags, or other suitable cover.

The invention consists essentially in attaching to the barrel of therifle by means of a strap, clip, or other fastening, a small mirrorarranged at an angle of 45o to the usual line of sight, andsubstantially horizontal therewith.

But in order that the invention may be clearly comprehended, I now referto the accompanying drawings, in which,

Figure l is a perspective view of my periscope atachment for sightingfrom the right, while Fig. 2 is a similar View for sighting from theleft side. y

Fig. 3 is a partial elevation of a rifle showing the periscopeattachment in position.

Fig. 4 is an elevation showing the method of using the attachment, whileFig. 5 illustrates in perspective an attachment in which a double mirroris pivoted and may be changed from one side or the other according tothe position taken up by the person aiming.

The same reference letters indicate the same or corresponding parts.

A is a mirror preferably secured in a suitable casing B, having asemi-circular portion C capable of fitting over the barrel of a rifle inline with the sights and behind the rear sight. D is a flexible strapfor fastening the attachment in position on the barrel by means of thebuttons, E, E. F is the barrel, and G is a portion of the stock. J is asighting aperture in the casing which is also open at its front K.

In using the periscope attachment the muzzle end of the rifle is restedon any convenient object, such as a sandbag, while the rifleman takes upa position at one side facing the mirror thereby enabling him to alinethe sights by reflection. At the same time he grasps the butt with onehand the thumb of his other hand being in contact with the trigger ofthe rifle as clearly shown in Fig. 4.

In Fig. 5, the mirror is a double one and with the casing B is madeadjustable on the lower portion C around a pivot pin I-I or the likepreferably situated between the two refleeting faces of the mirror sothat the sights of the rifle may be aligned from either side accordingas the facilities afforded by the cover require.

Having thus described my invention, what I claim as new and desire toprotect by Letters Patent, is

1. A periscope attachment for rifles, comprising a casing portion; asupporting portion whereon said casing is rotatably mounted, adapted todetachably engage the barrel of the rifle behind the rear sight; and adouble mirror within said casing arranged in the line of the sights andat an angle of approximately 45 thereto; said mirror.being moved by therotation of said casing in one direction or the other into position toenable the marksman to aline the sights from either side of the rifle bydirect reflection.

2. A periscope attachment for rifles, comprising a casing rotatablymounted upon the rifle barrel behind the rear sight; and a double mirrorwithin said casing arranged in the line of the sights and at an angle ofapproximately 45 thereto; said mirror being moved by the rotation ofsaid casing in one direction or the other into position to enable themarlrsman to aline the sights from either side of the rifle by directreflection.

3. A periscope attachment for rifles, comprising a box-like casingmounted upon the barrel of the rifle behind the rearsight and having itsfront open; and a vertical double mirror within said casing arranged inthe line of the sights and at an angle of approximately 45 thereto; saidcasing having sight openings in its sides.. located opposite saidmirror, said mirror being moved by the rotation of said casing in onedirection or the other into position to enable the marksman to aline thesights from either side of the rifle by reflection directly visiblethrough the adjacent sight-opening.

In testimony whereof I have hereunto set my hand.

EBENEZER REGINALD MORRIS.
